Abstract:Older adults access critical resources online, including bank, retirement, and health insurance accounts. Thus, it is necessary to protect their accounts so they can confidently use these services that are increasingly being moved online. Two-factor authentication (2FA) protects online assets through efficient and robust authentication, but adoption and usability remain a challenge. Our in-depth qualitative research focuses on ten older adults’ (≥ 60 years) sustained (non)usage of 2FA for thirty days. Participants’ limited adoption of the security keys stemmed from its non-inclusive design, lack of tangible benefits, inconsistent instructions, and device dependencies. We propose design modifications, age-friendly instructions, effective risk communication, and appropriate assistance to encourage 2FA adoption among older adults and institutions entrusted with their data. We also introduce the concept of ‘Security Caregivers,’ who can ensure security and digital independence for the aging population
